Claims. ('01. fill-93) times desired, as, for example, when printing checks. Means are provided whereby some humhers are printed in the ordinary way and others in the latter way. In the instance chosen to illustrate the invention, the machine automatically prints the items from a group of punched cards as usual, with zeros only to the right of the highest digit of each number, and it automatically prints the totals with zeros both to the right and also to the left of. said digits.

The invention has for one of its objects to provide means settablehy the operator of the machine to precletermine which of a series or printing elements shall have the mode of operation above outlined and which shall not. The controls may he are-set in different ways, some of them so as always to print zeros only at the right of the highest digit and others so as to print in that manner in some machine cycles, and in other cycles to print zeros also to the left of the highest digit. Preferably, the controls may also he set so as not to print zeros at all. It is thus possible for the operator to set the mechanism up in a variety of ways, and to set it in one way for one job and to change the setting for another job. To the above and other ends which will appear in the course of the description, the invention consists of certain features of construction and certaincomhinations and arrangements of parts,

all of which will be fully described herein and particularly pointed out in the claims.

One instance of the invention is illustrated in the accompanying drawings, in which Fig. l is a right hand side elevation with parts of and. associated with the invention, with some parts in section and some broken away;

Fig. 4 is a iront elevation of Fig. 3, partly in section on the line l-fl of Fig. 3, and with some parts omitted;

Figs. 5-4.0, inclusive, on a larger scale than the other figures, are right hand viewsof the upper. end portion of a single hammer latch and its controls, said controls being in different positions in the difierentviews. Figs. 8. 9, and 10 show three settings of the controls, with the operating device in normal position; and Figs. 5, 6, and 7 show, respectively, the same three settings but with said operating device in operated position;

Fig. ii is a front view of three oi the hammer latches and their controls, with a certain flange in section just inside the right hand frame piece and showing some of the operating and control mechanism of 2. Powers tabulating machine having the invention applied thereto;

Fig. 2 is a fragmentary view of a portion of Fig. l but on a larger scale than Fig. l and with some parts removed; Fig. 3 is a right hand view of the moo in section on the line iili of Fig. 8;

Fig. 12 is a fragmentary top view of a few of the controls and the device which operates them;

and

Fig. 13 shows a sample of printing according to the invention.

By way of illustration, the invention is shown applied to a Powers 'tabulating machine of the sort described in the patent to Lasker and Mueller No. 2,323,816 patented July'ii, 1943, and. also in the application of J. Mueller for Letters Patent for Accounting machine filed February 1, 1940,

S. N. 316,739. In said machine, punched cards are fed through a sensing chamber where such sensing pins as find holes raise set pins 20, Fig. 1

which, through Bowden wires in the translator 2 l set up in the machine stops which control the various functions of the machine and among other things, control the setting of type bars 22, Fig. 3. The machine comprises a base section 23, Fig. 1, surmounted by a head section having right and left irame members is and two ve shafts, namely, a forward shaft 25 and a rear shalt 125, each of which makes one, rotation per machine cycle. Cross bars 21 support accumulators as which are operated by rack teeth on the lower parts of the type bars 22. The paper carriage 8B3 supports a platen l 3 l against which the types 32 on the type bar aredriven to print.

The type hammers 33, Fig. 3, are pivoted to a framehar 3B and when fired are impelled .by springs 35 to strike pins 36 one for each type bar which pins drive the types against the paper.

The type hers have a restoring bar t l and are normally latched against operation by latches iii, a series of which are pivoted on a frame bar 8 l When any type liar rises above itszero printing position, a link 32 moves downward permittime a spring E3 to swing clockwise a release link 44 so as to bring a shoulder on said link into the nism differs slightly in detail from, but is subpath oi movement of a flange on a print bar 45. t t y the Same as, that described in the P Said print bar at the moment of printing makes a application N- and 85 described a short vibration toward the rear releasing any Claimed in the pp a on for etters Patent latch whose release link 41 has been moved into 5 filed y John Mueller a y 6, 9 B- engagement with it.

flange 53 and the connectors 41 downward from #1 their normal position instead of upward. Each connector has a lug 65, shown in the form of a hook, so placed that if the link i be set in its lowest position shown in Fig. this lug will stand normally a little above lug 50 of the next latch to the right, and if then the sleeve 54 be rocked clockwise to the position shown in Fig. 7, this lug will move down in front of the lug 50 thus locking the two latches 51 together. When the connectors in any field are set in this position, the swinging of any latch will swing all the rest of the latches in that field with it so that all of said latches'will be released at every printing operation, printing thezeros before as well as after the' other digits. I I v In the Powers machine as manufacturd the sleeve corresponding to the sleeve 54, has'heretofore been rocked counterclockwise under card control by'the means now tobe described. A cam 65 on the drive shaft 25 rocks a follower lever '51 pivoted at 58 and carrying an upright link I0 which is urged clockwise (Figs. 1 and 3) about its pivot 'II by a spring I2. At its upper end said link has. an L-shaped opening 13 (Fig. 2) in which lies.

a pin I4 projecting from a lever which is pivoted on the same fixed stud It as a certain bell crank 'II (Fig. l) and the spring 12 normally holds the lever rearward with the forward edge of the opening I3 pressed against the pin 14, as shown. As the link is moved down and up by the cam 66, it rubs idly over the pin without operating the lever 15. In the latter part of each cycle, at the time when the sensing pins are moving up to sense the card, the link I0 is in its high position and the pin I4 is therefore in the lower party of the opening I3. When a card is sensed having a special control holefthe sensing pin for said hole pushes up the set pin 20, which, through Bowden wire 80 and pin 8 l, rocks a bell crank 82 which, through a link 83, engaging a pin 80 on link 10 rocks said link I0 leftward in Figs. 1, 2, and 3,.bringing the horizontal limb of the L-shaped opening 73 into engagement with the pin 16. When, inthe first part of the next cycle, the link .10 moves downward, it rocks the lever "I5 clockwise and holds it in rocked position until the printing has been done. At its forward end, said lever carries a link 86, which is pivoted at 85 (Fig. 4) to an arm 36 fast on the sleeve 50. The sleeve is thus rocked counter-clockwise under control of a card.

In order to prevent a card from causing the sleeve 5t to be rocked as just described on total taking operations, the following means are employed: The total taking control unit 8! of the Powers machine, includes certain cams and certain levers 80 which pull certain links 90. One of these, through hell crank 9i, link @2, bell crank 93, link 94, and arm 95, "pulls (rocks clockwise in Fig. l) a certain credit balance shaft at very early in the blank stroke and holds it pulled until near the end of the total stroke; and this shaft is utilized to disable the link I0 duringthat period. An arm 91 on said shaft put hes a link 98 which (Fig. 2) has a slot lilii engaging the pin M on link I0. On item cycles said link may be swung frontward, the pin moving in the slot; but on total taking the front end of the slot engages the pin and prevents the arm from swinging. To make this possible, the card controlled link 83 also engages the pin 14 by a slot and a spring I0! normally holds the pin in the front end of it. When a card having the control hole in it, is in the sensing chamber duringv a total taking operation, the link 8315 pushed frontward. but the link 10 is held in its rear positionby the link 98, and the link 83 j therefore only stretches the spring IIII without causing a rocking of the sleeve 54 to change the zero set-up.

drawings to cause all zeros to be printed, the following means are provided: A link I02 (Figs. 3 and 4), is guided at its upper end by the pin '85 of arm 86 of the sleeve 54, engaging in a longitudinal slot I03 in saidlink. Said link carries a plunger I04, which, when projected as shown in Fig. 4,lies above the end of the link 84 and, when said link I02 is pulled downward, the said plunger will pull down said link 84 and rock the sleeve 54 to depress the connectors as above described, so that in any field where the connectors have been set as in Fig. 10, all of the all zeros be printed only on total taking cycles.

The total taking control mechanism of the Powers tabulating. machine includes a so-called total shaft I06 which is "pulled (rocked counter-clockwise in Fig. l) by a link I01, the bell crank 11, and a link I08 which last is pivoted to said bell crank at H0 and is pulled by one of thelinks 90. The bell crank I1 is omitted in Fig.3 for clearness. The link I08 is prolonged at its upper end, where it is furnished with a pin or post III (Figs. 3 and 4) which engages in a slot H2 in the rearwardly inclined lower part of the link I02. A spring H3 holds said pin yieldingly in the upper end of the slot and transmits the downward motion of the link I08 when the latter is operated.

The operation of the described mechanism is as follows: On normal item cycles, the sleeve 50 remains in its middle position shown in all of the drawings except Figs. 5, 6, and '7, and the.

printing is of the style suitable for items. An

causes link 83 to swing link in frontward, whereupon said link, when pulled by the cam 66, rocks the lever l5 clockwise, pushing up on link and rocking the sleeve 54 counter-clockwise to set the printing to the style suitable for the alphabetic line of print. The link 84 carries the link I02 up with it, the slot H2 in the lower end of the latter sliding on the pin III and stretching the spring H3. On a total taking cycle the link I0 is held inactive by the link" 08, and the link I08 pulls down the link I02 and rocks the sleeve 55 clockwise, changing the set-up of the zero couplers to the style desired for totals, as shown in Figs. 5, 6, and 7. The link I02 carries the link at down with it, rocking the lever I5 counter-clockwise, but this does no harm.

The lever I5 is thus rocked from a normal middle position first in one direction and then in the other. It is held in'and returned to such middle position by a centering device comprising a. link IHI (Fig. 3) which is mounted'on a In Fig. 13, the designation "m" in the left hand column, has zeros printed only to the right of the highest digit, but no zero is desired in the alphabetic headin line between the "J" and the N. The controls in that field were therefore set as in Fig. 9, and a control hole was punched in the heading card. n the first cycle, therefore, the connectors, position shown in broken lines, and no zeros were printed. In the field at the right where amounts are printed, the connectors were set as in Fig. 10, in which zeros are normally printed only at the right; but on the total cycle they were moved downto the position of Fig. 7, and all zeros were printed.

The connectors are shown inxa form suitable for a plication to the manufactured Powers machine, which form may be modified in applications to other machines. Various other changes may be made in the details oi construction and arrangement without departing from the invention.
